Exercise is the physical activity that is done in order for an individual to become stronger as well as healthier (Merriam Webster). Carbon dioxide plays an important factor in the human body which is a gas that is the byproduct of the cellular metabolism which collects in the tissues. Afterwards it is cleared from tissues through the blood in the veins and carried by hemoglobin in the red blood cells and then removed from body through the lungs in the exhaled air (Medicine Net). The hypothesis that was made before the experiment started was that: If a subject exercise’s, then the subject’s body will produce more carbon dioxide due to the body’s need to create more energy through cellular respiration at the recovery stage. The hypothesis is …show more content…
This data right here is showing that the hypothesis was incorrect because at the rest stage there was more carbon dioxide output being produced with an average of 7.56 (according to table 1.2) while at the recovery stage there was less carbon dioxide being produced with an average of 7.02 (according to table 1.3). Also, graph 1.1 and 1.2 shows the difference between the breathing rate, time, and carbon dioxide output (pH color) and an interesting point is that in the rest stage the carbon dioxide output (pH probe) are all clustered around one another while in the recovery stage the carbon dioxide output (pH probe) are little more separated. These are the reasons why the hypothesis was incorrect. Some other conclusions that can be made is that the more an individual exercise, the more energy is going to be needed for the body to function …show more content…
Also, when the individuals get to the recovery stage after doing 3 minutes of jumping jacks and are about to breathe into the straw, a new straw should be placed because the other straw could be crushed which would not allow all of the breath to go in properly. The second suggested improvement addresses the concern of the plastic wrap not being taped properly to prevent carbon dioxide that is being gathered to leave the beaker. The way to fix that would be getting the plastic wrap and gluing every single part of the plastic wrap to ensure that it wouldn’t let any air out of the beaker. The third suggested improvement with the weakness being counting the breathing rate of an individual. The way it would be verified is having an other individual keep track of the timer and having another individual keep track of the number of breathes taken and writing it down on paper. Therefore, it would keep the data more accurate and fulfill the purpose of the experiment. Finally, the fourth suggested improvement with the weakness being the physical and daily activity of an individual on a daily basis. The best way to verify that is having individuals that play a sport like cross country, track and field, or even hiking where oxygen and carbon dioxide is used properly. Therefore, by picking an individual like that their breathing capacity would all be around the same and
Prior to intubation for a surgical procedure, the anesthesiologist administered a single dose of the neuromuscular blocking agent, succinylcholine, to a 23-year-old female to provide muscular relaxation during surgery and to facilitate the insertion of the endotracheal tube. Following this, the inhalation anesthetic was administered and the surgical procedure completed.
For further investigation, a larger sample size should be used, along with repeating the experiment on several different days to minimise the effect of random errors on each subject’s specific result. Reference List: BBC 2014, Respiration, BBC, accessed 1 September 2015,.
Submaximal and maximal exercise testing are two analytic methods that can be used to examine the cardiovascular, and cardiorespiratory fitness/health levels of the individual being examined. Submaximal testing is usually preferred over maximal mainly because the submaximal exam is more practical in a fitness/health environment. Both test require the individual being examined to perform controlled exercise on a(n) treadmill/ergometer until either steady state has consecutively been reached (submax), or the individual reaches their max (close to it). Being that both test are set to exceed time limits of more than 3 minutes we examine the use of the ATP-PC, Glycolytic, and Oxidative energy systems. Although a huge portion of the test involves the use of the oxidative energy system, we must remember that the three systems are co-occurrent.
The protocol and conceptual overview of these procedures can be found under the header, “Properties of Skeletal Muscle” in NPB 101L Physiology Lab Manual Second Edition (Bautista & Korber, 2009, 9-17). The test subject for this lab was the Northern Leopard frog whose spinal cord and brain were severed. In order to carry out the experiments, the materials needed were one medium length surgical scissor, two hemostats and glass dissecting probes, a nine and four inch string, a cup of Ringers saline solution with an eyedropper, and a hook electrode. The software used to analyze and record the data was the BIOPAC system.
Over a three week period a test subject was instructed to come to the exercise physiology lab once a week. The purpose of the first week was to determine the baseline test data for the participant. During this first week, the subject was asked how many hours of sleep they had gotten the night before and how much they weighed. The subject was then instructed to put on a heart monitor and wear an O2 apparatus and begin running on a treadmill. This treadmill was set at zero incline for the beginning of the run until three minutes had passed. At the three minute mark the incline increased by 2.5%. After this the incline was continuously increased by 2.5% every two minutes. During this process, the VO2 and RER exchange rate of the subject was being tracked through the O2 apparatus. Their heart rate was recorded every 15 seconds. In addition, the subject was asked their perceived exertion at every increase in incline. The subject continued to run until they could not run anymore, at this time they would hop off the treadmill.
In this lab, I took two recordings of my heart using an electrocardiogram. An electrocardiogram, EKG pg. 628 Y and pg. 688 D, is a recording of the heart's electrical impulses, action potentials, going through the heart. The different phases of the EKG are referred to as waves; the P wave, QRS Complex, and the T wave. These waves each signify the different things that are occurring in the heart. For example, the P wave occurs when the sinoatrial (SA) node, aka the pacemaker, fires an action potential. This causes the atria, which is currently full of blood, to depolarize and to contract, aka atrial systole. The signal travels from the SA node to the atrioventricular (AV) node during the P-Q segment of the EKG. The AV node purposefully delays
Because as you exercise the cells in your body will need more oxygen. So therefore, the heart will pump harder to get more oxygen
The reason why is that exercising gets your blood pumping which brings more oxygen to your muscles. According to table #1, it can be seen that most of the numbers under the difference column are positive which means that these people’s squeezing rate increased when they exercised first. Based on graph #1, you can see that more people increased by the height of the bar. Both the table and the graph support that if a person exercises first , he/she will be able to squeeze a clothespin more times in a minute than a person who rests
There are many tools to assess functional exercise capacity most of which provide good information about body system. The most popular clinical exercise tests are stair climbing, a 6MWT, a shuttle-walk test, detection of exercise-induced asthma, a cardiac stress test and a cardiopulmonary exercise test) (ATS, 2002). In the past, the functional exercise capacity was assessed by asking patients “How many flights of stairs can you climb or how many blocks can you walk?”; but, this assessment was a subjective measurement. In addition, the first objective tool was in 1960s which was 12 minute walking test; however, it was so exhausting for patients. As a result from that, a 6 minute walking test (6MWT) was found to be used as an objective measurement tool for functional exercise capacity in patients with mild or moderate respiratory diseases and cardiac diseases (ATS, 2002). Many studies have concluded that 6MWT is inexpensive test and“… it is easy to administer, better tolerated, and more reflective of activities of daily living than the other walk tests” (ATS, 2002). Therefore, this essay will describe the 6MWT and comment on administration, application, reliability and validity based on the literature reviews.
•While exercising your lungs tries to increase the intake of oxygen as well as release the carbon dioxide.
The Queens College/McArdle Step Test, the Rockport One Mile Walk Test, and the 1.5 Mile Run Test are three different field tests that were performed in this lab that were used to measure and predict an individual’s aerobic capacity. The measurement of aerobic capacity, or VO2 max, is a valid way to assess an individual’s cardiorespiratory fitness level. VO2 max refers to the maximal amount of oxygen an individual utilizes during intensive exercise. A higher VO2 max demonstrates a more efficient cardiorespiratory system as an individual with a higher VO2 max can sustain a higher intensity for a longer
This force transfers into the arteries and arterioles in other parts of the body as the blood moves away from the heart. Once the intensity drops and the stress on the heart decreases, the pressure in the arteries also reduces due to the less forceful contractions. Therefore, the hypotheses were accepted based on the averages of the data collected during the experiment. However, in order to have more accurate data, a larger sample size would be needed. In addition, using machines to measure heart rate and blood pressure could make the data more accurate than the process that was used in this experiment. Increased accuracy could also have been seen if there were more trials done when taking heart rate and blood pressure during the exercise stages and then averaging those
AIM: - the aim of this experiment is to find out what the effects of exercise are on the heart rate. And to record these results in various formats. VARIABLES: - * Type of exercise * Duration of exercise * Intensity of exercise * Stage of respiration
“With the exception of nutrition, more fallacies exist in the area of exercise than in any other area of health” (Dintiman, Stone, Pennington, & Davis, 1984). Exercise produces significant physical and mental benefits and is extremely vital to life. It substantially improves stamina, strengthens and tones muscles, helps prevent diseases, enhances flexibility, controls weight, and prolongs the quality of life. In order to gain all the benefits from exercise and be truly healthy, it is very important to understand and take action with both types of exercise: anaerobic and aerobic. With the combination of aerobic and anaerobic exercise, an individual will greatly increase their overall health and wellness significantly.
